General Description
The Dual-Band Tri-Mode Power
Amplifier Module (PAM) offers a
highly integrated solution for
CDMA dual-band tri-mode
handsets. The integrated solution
leads to improvements in cost,
size, performance, and reliability.
This PAM also offers several
features that will make handset
design more flexible and robust.
The module contains two power
amplifiers (PCS and Cellular PAs),
two driver amplifiers with power
control and bias circuits.
The cellular power amplifiers
provide: 32.5 dBm Pout and 47%
Power Added Efficiency (PAE) at
3.4 V in AMPS mode, and 28.5
dBm Pout and 29% PAE at 3.4 V in
cellular CDMA mode. While the
PCS power amplifier achieves 28.5
dBm Pout and 28 % PAE at 3.4V in
PCS mode. The PAM is designed
with dynamic bias control to
optimize the PAE at low output
power in PCS and cellular CDMA
mode to maximize the system talk
time.
The surface mount RF MultiPak
insures cost, size, and high volume
manufacturing advantages over
other traditional approaches.
